Solve the following inequality for w then simplify <br> -w+9&gt;6w+8
Alla [95]

Answer:

\displaystyle (-\infty,\frac{1}{7})

Step-by-step explanation:

<u>Inequalities</u>

To solve the inequality:

-w+9>6w+8

We need to perform the required operations on both sides of the inequality to have the variable w isolated.

First, we subtract 9:

-w+9>6w+8

-w>6w+8-9

Subtracting 6w:

-w-6w>+8-9

Operating:

-7w>-1

Now we divide by -7 but recall that when dividing by a negative number, we must flip the inequality sign:

\displaystyle w

Operating:

\displaystyle w

Solution:

\mathbf{\displaystyle (-\infty,\frac{1}{7})}

Algebra help needed
lesantik [10]

Answer:

The ball will reach the ground when h=0.

Set the equation equal to 0.

0=-8(2 t-4)(t+1)

t=-1,2

Step-by-step explanation:

The height of a golf ball after it has been hit from the top of a hill can be modeled by the equation

h=-8(2 t-4)(t+1),

where h is the height in feet and t is time in seconds.  

When ball will reach the ground the distance between ball and ground is 0. So, the ball will reach the ground when h=0.

To find the time it takes for the ball to reach the ground,  set the equation equal to 0 and use the Zero Product Property to solve for $t$.

h=-8(2 t-4)(t+1)

\Rightarrow 0=-8(2 t-4)(t+1)

Solve the equation using the Zero Product Property.

2t-4=0\Rightarrow t=\dfrac{4}{2}=2

t+1=0\Rightarrow t=-1

So, t=-1,2
